These balls are fun... I just did a shoot for Disney Channel with these. The kids were zipped inside them and they raced around a padded course. I was running ahead of them backwards at top speed trying not to get mowed down by some very energetic competitors. It was a lot of fun and the closest I've ever gotten to being Indiana Jones (the opening of Raiders). Yeah for big clear balls!

Zorbing has become a sport/attraction in N Zealand. We shot them rolling down hill in NZ both wet with water(to slide in) and people inside and dry just tumbling around inside. The best shot was inside with a plastic bag over all but the end of the lens three people tumbling around in a "wet" zorb..... a kinda intimacy which is not for everyone.

So you pay the fee ride the truck to the top of a fair hill while the balls come up a ball ramp to the top, you get in and they roll it down the hill..... One guy kept on his feet almost all the way down!!!!
